snip
The ways to dereference a hash are
# treat $ref as a hash variable
%$ref
# treat $ref as a hash variable, useful for when the reference is not
a simple scalar
%{$ref}
#index into $ref
$ref->{key}
# bulkier way of indexing into $ref, the -> operator is preferred
${$ref}{key}
# take a slice of $ref
@{$ref}{qw/k1 k2 k3/}
